Atom interferometry shows high sensitivity for inertial measurements in the laboratory, but it faces difficulties field applications because of a trade-off between and size. Therefore, there is an urgent need to develop small sensor with resolution measuring acceleration rotation navigation applications. Presented here miniaturized capable simultaneously based on high-resolution dual atom interferometers. A head integrated within volume 100 l, which vacuum chambers are fabricated by bonding...
This study systematically investigates the temporal characteristics of a high-pressure CO2 master oscillator power amplifier (MOPA) system under tunable spectral lines. Based on continuously oscillator–amplifier system, we experimentally measured variation in laser pulse width before and after amplification at different lines, with operating pressures 7 atm 3 atm, respectively. The results indicate that, for most remained nearly unchanged amplification. However, certain distinct phenomenon...
We present a highly efficient and cost-effective watt-level deep-ultraviolet laser operating at 266 nm. Type-I phase-matching LBO crystals type-I BBO were used for frequency doubling fourth-harmonic generation, respectively. The highest 1.82 W average power of the nm was obtained from nonlinear conversion repetition rate 30 kHz pump 18.8 W. efficiency diode to scales up 10.7%. This is, our knowledge, ever reported generated single-end-pumped acousto-optic Q-switched system.
Sarcastic comments are often used to express dissatisfaction with products or events. Mining the topics and targets can provide clues for analyzing underlying reasons behind sarcasm, which helps understand user demands improve service. Existing research mainly focuses on mining single facet of such as topic target, ignoring complex interrelations between them. To overcome above challenges, this paper proposes a Heterogeneous Information Network fused Context-Aware Contrastive Learning...
Operating atom-interferometer gyroscopes outside a laboratory environment is challenging primarily owing to the instability of laser systems. To enhance thermal stability free-space systems, compact system using fiber lasers and all-quartz-jointed optical modules was developed for dual-atom-interferometer gyroscope. Millimeter-scale elements jointed on quartz plates with identical supports, ensure power facilitate component upgrades. The primary diode locked modulation transfer spectrum Rb...
